国产2024-T351大规格厚板将在某型飞机首次选用,针对该材料开展硫酸阳极化、硼硫酸阳极化、阿洛丁1000、阿洛丁1200S等表面防护工艺应用研究,基于国产材料与进口材料各项性能基本相当,因此采用了与进口材料相同的电压、槽液成分、温度及时间等工艺参数,并对照进口材料的漆层结合力、盐雾试验等验收标准,判定表面防护工艺的耐蚀性水平及差异,为防腐蚀设计提供技术支持。
Domestic large-size 2024-T351 heavy plate will be the first selection of a plane for the material to carry out anodic oxidation of sulfuric acid, boron and sulfuric acid anodizing, Alodin 1000, Alodin 1200S and other surface protection technology application research, based on domestic materials and imports The performance of the material is basically the same, so the same voltage with imported materials, bath composition, temperature and time and other process parameters, and control of imported materials, paint adhesion, salt spray test acceptance criteria to determine the surface protection process Corrosion resistance levels and differences for corrosion protection design to provide technical support.
